Sigma has announced it will add a 23mm F1.4 DC DN to its range of APS-C mirrorless-specific lenses. The 23mm will initially be available for Sony E, Leica L and Fujifilm X mounts, giving a 35mm-equivalent field of view.
Its launch comes four and a half years after the launch of the most recent DC DN prime, and becomes the first one not to be available for Micro Four Thirds or Canon EF-M. It means the DC DN range of 16mm, 23mm, 30mm and 56mm F1.4 primes now offer 24, 35, 45 and 85mm equivalents for APS-C shooters of Sony, L-mount and Fujifilm cameras.
The 23mm F1.4 DC DN is part of the company’s Contemporary range of mid-price lenses. It’s one of the large lenses in the DC DN series: 66mm wide and 77mm long (2.6 x 3.0″).
The lens takes the same 52mm filters as its 30mm F1.4 DC DN sibling and comes with a petal-style hood. Its relatively complex 13 element/10 group design includes three Super-Low Dispersion (SLD) elements and two aspherical elements, which contributes to its 340g (12oz) weight.
The Sigma takes a middle ground, size and weight-wise, between the Tokina and Viltrox 23mm F1.4s and Fujifilm’s own LM WR lens. Its list price of $549 also places it in the midst of this company. It will be available from late April 2023.
